Here's a little more about the movable greenhouse, it's 14 x 20 and it's made out of 1-3/8" chain link top rail,it slides on 2 x 12 lumber that is bolted to fencing U channel set in concrete. It has thermostatically controlled vents and fan,vents open via damper controller, shelves on north side are in the folded down position in picture ,that's where the heat mats and flats go in late winter,also has automatic drip system installed, I remove most of the end polycarbonate end panels when it gets really hot like today ,it was 100 degrees and they stay off until fall,the whole idea of a movable greenhouse is so you avoid buildup of diseases in the soil and as you can see it works,this is year 5 or 6. This is not a kit,they are to spendy for me, this costs about $1500.00 to build.
